Seawater samples were collected from April 6 to September 6, 2017 in the Southern Yellow Sea, China where green tides often occurred, and analyzed for nutrients, dissolved organic carbon (DOC), and fluorescent dissolved organic matter (FDOM). The DOC concentrations increased significantly in the green tide areas by approximately 1.2 times compared to those in the non-green tide areas. From the large-scale outbreak to the complete dissipation of the green tide, the fluorescence intensities of the four FDOM fluorescent components identified in the green tide areas were significantly higher than those in the non-green tide areas. During the extinction period, the fluorescence intensities of the three humus-like components and one protein-like component were approximately 1.8 and 1.3 times higher than those in the non-green tide areas, respectively. These findings suggested that the outbreak of green tide could release DOM into water and affect the biogeochemical cycle in green tide regions.
于 2017 年 4 月 6 日至 9 月 6 日在中国黄海南部采集了海水样本，该地区经常发生绿潮，并对营养物质、溶解有机碳 (DOC) 和荧光溶解有机物 (FDOM) 进行了分析。与非绿潮区相比，绿潮区的 DOC 浓度显著增加了约 1.2 倍。从绿潮的大规模爆发到完全消散，在绿潮区鉴定出的四种 FDOM 荧光成分的荧光强度明显高于非绿潮区。在消亡期，三个腐殖质样成分和一个蛋白质样成分的荧光强度分别比非绿潮区高约 1.8 倍和 1.3 倍。这些发现表明，绿潮的爆发可能会将 DOM 释放到水中，并影响绿潮区的生物地球化学循环。
